CAR-WHEEL.

SPECIFICATION forming part of Iietters Patent No. 631,692, dated August 22, 1899.

Application filed Tune' 20,1899.. Serial No. 721,243. (No model.)

To all whom it may concern.-

Be it known that I, JOHN W. BREEDING, a citizen of the United States, residing at'Bisbee, in the county of Cochise and Territory of Arizona, have invented a new and useful Improvementin Oar-Wheels, of which the following is a specification.

My invention is an improvement in carwheels, having for an object to provide an improved construction by which to prevent the wheel from climbing the track-rail and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is avertical sectional view of a car-wheel provided with my improvements in place on arail. Fig. 2 is a face View of the wheel. Fig. 3 is a detail enlarged section of the rim portion of the wheel. Fig. 4 is a detail section on about line 4 4: of Fig. 3. Fig. 5 illustrates in detail one of the removable blocks for closing the loading-opening, and Fig. 6 is a partial detail edge view.

The car-wheel A is formed with the tread B and the flange O, and may in general respects be of any suitable construction.

As is well known, car-wheels, especially when somewhat worn, have a tendency to climb the rail, which results in many acci- By my invention I provide the flange ing movement of the wheel-flange alongside the track-rail, and thus avoid all accidents resulting from the climbing of the wheel upon the rail.

In the construction shown I provide the flange O in its inner face with a circumferentially-extended undercut raceway D for the balls E. This raceway is arranged about midway between the tread B and the outer edge of the flange O and is so formed rela= tively to the balls E as to permit the latter to protrude from the inner face of the flange Osufficiently far to operate upon the rail, as before described. It is desired to prevent the balls from moving bodily circumferentially of the wheel, and for such reason I prefer to divide the raceway D by cross-partitions F F and G G into a series of segmental sections. The partitions G are arranged alternately with the partitions F and are removable to facilitate loading the balls into the raceway. I

To thisend I provide the wheel-flange with undercut slots H, intersecting the raceway D, and form the partitions G to fit the slots H, as will be understood from Figs. 2, 3, and 5. Wheninserted, as shown in Fig. 2, the parti tion-blocks are suitably held, it may be, by means of screws G, as shown in Fig. 3. The blocks G, it will be noticed, operate both to form a partition for abutment by the balls in theraceway and to close the loading-opening,

which leads through the' undercut raceway for the balls.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. A car-wheel having a tread and a flange and provided with balls supported in its flange and protruding from the inner face thereof and adapted to turn in a direction radial to the wheel whereby to avoid any lifting movement of the wheel-flange alongside the trackrail, substantially as set forth.

2. A car-wheel provided with a tread and a flange and provided in the inner face of its flange witha circumferentially-extending undercut raceway and with balls held in said raceway and protruding from the inner face of the flange substantially as set forth.

3. A car-wheel provided with a tread and a flange and having in the inner face of its flange a circumferentially-extended raceway dividedby cross-partitions into segmental opening and extending across the raceway whereby to form a partition for abutment by 10 the balls in the raceway, substantially as set JOHN \V. BREEDING.

sections, and balls held in said raceway and protruding from the inner face of the wheelfiange, substantially as set forth.

5 in its inner face with a eireumferentially-extended undercut raceway for balls and with a loading-opening leading to said raceway, and the removable block fitting said loading- \Vitnesses:
